ROGER W. GRAVES, OF BUFFALO, NEW YORK.

STA RCH-TABLE.

SPECIFICATION forming part of Letters Patent No. 246,671, dated September 6, 1881.

Application filed August 1, 1881.

To all whom it may concern:

Bc it known that I, ROGER W. GRAVES, of the city ofBuffalo, iu the county of Erie and State of New York, have invented new and useful Improvements in Starch -Tables, ot' which the following is a specication.

This invention relates to an improved adjusting device, whereby the tables or depositing-troughs in starch-factories can be readily adjusted so as to cause the liquid to iiow evenly and with the proper velocity over the same. Heretofore starch-tables have been adjusted by means of screws and nuts arranged underneath the tables, but these adjusting, devices are reached with difficulty and require the services of two men-one below the tables to turn the adjusting-nuts and one above to level the tables.

The object of my invention is the construction of a simple adjusting contrivance which can be readily operated by persons on the tables, thereby rendering the operation ot' adjusting the tables more convenient andthe adjustment more accurate than heretofore.

Myinvention consists ofthe particular construction of the adjusting device, as hereinafter described, and pointed out in the claim.

In the accompanying dra-wings, Figure l is a longitudinal sectional elevation of a starchtable provided with my improvement. Fig.`2 is a cross-section ot' two starch-tables. Fig. 3 is a longitudinal section, and Fig. 4 a cross` section, both on au enlarged scale, ot' that portion or" a starch-table provided with my adjusting device.`

Lilie letters of reference rei'er to like the several gures.

A represents the starch-tables or depositingtroughs, consisting ofvshallow troughs or gutters, constructed in any usual and well-known manner.

B represents the cross-pieces upon which the starch-tables are supported, and C the longitudinal girders upon which the cross-pieces B rest. t

D represents the horizontal timbers of the building which support the starch-tables.

E represents adjustable vertical bolts, which support the tables A upon the timbers D.

parts in (No model.)

are held against turning'by spurs or pinsf,A

formed ou their upper sides and entering recesses in the girders. Each table is supported by two bolts, E. upon each timber D. By turning each bolt E in one or the other direction that portion ofthe table resting upon the bolt is raised or lowered accordingly, whereby anydeviation of the table from the correct position by the sagging, settling, or warping ot' the supports, or from any other cause, is readily compensated for and the proper inclination readily maintained in every part of each. table independent of the other tables which may be arranged on the same supports or door. The screw-bolts E are adjusted i'roni above by the person who a pplies the level to the tables, thereby avoiding the necessity of getting under the tables for the purpose ot' reaching the adjusting devices, and simplifying and expediting the operation of adjust-ing the tables and permitting ot' a more accurate adjustment or" the same, as the person adjusting the tables can keep his eye on the level while adjusting the bolts.

I claim as my inventionlhe combination, with a starch-table ordepositing-trough, A, ofsupporting-bolts E, resting upon the timbers orothcriixed supports, D, underneath the tables, passing` through screwnuts F, attached to the girders ot' the tables and extending upwardly within convenient reach of persons on the tables, substantially as set forth.
